This bolt has a nut 30 which is preferably provided with an inwardly extending reduced end portion 32 which is internally recessed and threadedly adapted to receive the threaded end portion 34 of the bolt 28. If desired any suitable packing rings 35 and 38 may be provided to prevent the escape of steam through the open portions I6 and I8.

The tubular section 24 has a nipple or circular tubular extension 4I] which is threadedly adapted to receive a nozzle cap 42. This nipple may extend at right angles to the longitudinal axis of the bolt 28. The nozzle cap 42 has a preferably V-shaped slot 44 through which, in operation, a blast of steam or air issues at a high velocity to shred the molten materials into mineral wool fibers. i

In operation, the tubular section 24 may be turned with respect to tubular member I2 by any `suitable instrument such as ior instance a wrench. In order, however, to make certain that the tubular section 24 remains in its desired angular position with respect to thetubular section I2, I preferably provide the tubular member I2 with two spaced apart ears 46 and 48. These ears are internally recessed and are threadedly adapted to receive inwardly extending threaded screw bolts 5G and 52, which serve to adjustably secure an upwardly extending ear 54 on the tubular member 24 in any desired angular position between the ears 46 and 48.

Referring now to Figure l, in operation, the nozzle means I is connected to the air or steam supply pipe I2 in such a position that a stream of lava issuing from any suitable cupola or melting furnace B falls upon the preferably V-shaped blast of steam which shreds the lava and directs the combined blast of steam or air and lava into any suitable blow chamber 58 which is preferably, though not necessarily provided with a movable iioor or conveyor 60.

From the foregoing description of the various parts of the nozzles, its operation may be readily understood. When it is desired to lower the blast, the screw bolt 50 is retracted and screw bolt 52 advanced. When it is desired to move the nozzle cap 42 to the left or to the right the nozzle cap may be turned to the right or the left as may be desired with a monkey wrench or the like by turning the nozzle on threaded supply pipe I4.

If desired the screw bolts 50 and 52 may be withdrawn and the front of the nozzle may be moved upwardly or downwardly by any suitable wrench.

Having described my invention, I now make the following claims: Y

l. A mineral wool blow cap of the character described, said blow cap including a rigid tubular fluid inlet section and a rigid ltubular fluid outlet section, each of said sections being detachably and pivotally secured substantially at a right angle to each other, said tubular outlet section being provided with an outwardly extending nipple portion including a nozzle member adapted for directing a lluid blast substantially at right angles to the main center line of the tubular outlet section, said blow cap being also provided with a plurality of ears mounted substantially in alignment with each other, at least one of said ears projecting from each of said tubular sections and at least two of said ears projecting from one of said sections on opposite sides of said one of said ears, each of said last mentioned two earsV being provided with threaded recessed portions and with a threaded bolt adapted to engage said one of said ears at various positions intermediate of the last mentioned two ears.

2. A mineral wool blow cap of the character described, said blow cap including a rigid tubular V iluid inlet section and a rigid tubular iluid outlet section, each of said sections being detachably and pivotally secured substantially at a right angle to each other, said tubular outlet section including a nozzle member adapted for directing a fluid blast substantially at right angles to the main center line of the tubular outlet section, said blow cap being also provided with a plurality of rigid extensions mounted substantially in alignment with each other, at least one of said extensions projecting from each of said tubular sections and at least two of said extensions projecting from one of said sections on opposite sides of said one of said extensions, each of said last mentioned two extensions being provided with threaded recessed portions and .with an elongated threaded means adapted to engage said one of said extensions at various positions intermediate of the last mentioned two extensions.
